Detailed Description

An OrthoGPUProducer layer to draw roads.

Author:: Antoine Begault, Guillaume Piolat

Member Enumeration Documentation

enum proland::RoadOrthoLayer::roadType

Predefined type for roads.

Used for drawing and managing roads.

Enumerator:

ROAD	Basic road.
UNKNOWN	Undefined.
BRIDGE	Bridge linking 2 roads, passing on top of another.

Constructor & Destructor Documentation

proland::RoadOrthoLayer::RoadOrthoLayer	(	ptr< GraphProducer >	graphProducer,
		ptr< Program >	layerProgram,
		int	displayLevel = `0`,
		bool	quality = `true`,
		vec4f	color = `vec4f(0, 0, 0, 0)`,
		vec4f	dirt = `vec4f(0, 0, 0, 0)`,
		vec4f	border = `vec4f(1, 1, 1, 0)`,
		float	border_width = `1.2f`,
		float	inner_border_width = `2.0f`,
		bool	deform = `false`
	)

Creates a new RoadOrthoLayer.

Parameters:

	graphProducer	the GraphProducer that produces the graphs to be drawn by this layer.
	layerProgram	the Program to be used to draw the graphs.
	displayLevel	the quadtree level at which the display of this layer must start.
	quality	enable or not the quality mode (better display).
	color	roads color (default 0:0:0).
	dirt	small dirt paths color.
	border	roads border color.
	border_width	roads border width.
	inner_border_width	roads inner border width.
	deform	true if the produced tiles will be mapped on a spherical terrain.

virtual proland::RoadOrthoLayer::~RoadOrthoLayer ( ) [virtual]

Deletes this RoadOrthoLayer.

proland::RoadOrthoLayer::RoadOrthoLayer ( ) [protected]

Creates an uninitialized RoadOrthoLayer.

Member Function Documentation

		vec2d *	nx = `NULL`,
		vec2d *	ny = `NULL`,
		vec2d *	lx = `NULL`,
		vec2d *	ly = `NULL`
	)			`[private]`

Draws a road end white stripe between 2 points.

Parameters:

	fb	a FrameBuffer.
	p	Coordinates of the first point.
	n	Coordinates of the second point.
	w	The line width.
	scale	The scale, based on the current display level.

float proland::RoadOrthoLayer::getFlatLength	(	NodePtr	p,
		vec2d	q,
		CurvePtr	path
	)			`[private]`

Returns the longest flat length of curves around a node.

Parameters:

	p	a Node.
	q	a position.
	path	a Curve.

Returns:: the longest flat length around node p.

float proland::RoadOrthoLayer::getLengthWithoutStripes	(	CurvePtr	p,
		CurveData *	data,
		bool	start
	)			`[private]`

Returns the length of a curve to be drawn without stripes.

Parameters:

	p	a curve.
	data	the CurveData containing data about Curve p.
	start	if true, will compute from the starting node. Else, from the end node.
